Hi All,

I am having issues with Configuring PXE server to Install RHEL 7 running on EFI. The Same server is configured to Install RHEL 7 with Legacy BIOS. Below is Network Configuration. I am using http to share the Images and is working file for clients running with BIOS.

Target Network is                                           : 192.168.50.0/255.255.255.0

Required DHCP range is                                  : 192.168.50.71  to 192.168.50.100

TFTPSERVER/DHCP Server is                     : 192.168.50.11

OS Versions : RHEL 7

Output file for /etc/xinetd.d./tftp

default: off

description: The tftp server serves files using the trivial file transfer \

protocol. The tftp protocol is often used to boot diskless \

workstations, download configuration files to network-aware printers, \

and to start the installation process for some operating systems.
